I own a .30 Carbine. I also load for .357 Mag/.38 special.

If I were doing the buying I would get the .357 Mag for a few reasons.


1 Less expensive for ammo, that is easier to find. (.30 carbine is not something on the shelf of any store that sells ammo.)

2 Easier to load for, with a larger margin for error. (Most loads for .30 Carbine have a spread of 1 grain from start to max.)

3 with carbide dies you do not have to lube .357 mag/.38spcl cases. You have to lube .30 carbine even with carbide dies. When you lube cases. Afterwards you have to remove the lube before firing them. If not dangerous pressures on the breech face result.


Note I load for both. I love my .30 carbine. I hate trying to find brass for it, and hunting down the brass it slings out. I tend to find about 8 of every 10 fired. The other two seem to evaporate into the air.
